Description

Technical Field

[0001] This utility model relates to the field of design and measurement technology, and in particular to a design and measurement device for highway construction. Background Technology

[0002] Highway construction is the process of transforming highway engineering design drawings into physical roads. Highway construction is a systematic project that integrates engineering technology, project management, and environmental protection. Its core objective is to build safe, durable, and comfortable road facilities within the budget and timeframe.

[0003] Early highway construction relied mainly on simple tools for measurement, which was inefficient and prone to errors. In particular, it was difficult to ensure accuracy in complex terrains such as mountains and rivers. With the advancement of highway engineering technology, the upgrading of construction needs, and the digital transformation of the industry, the limitations of traditional measurement methods and the urgent need for high precision and efficiency in modern engineering have led to the need for a design measurement device for highway construction.

[0004] Currently, commercially available highway construction design and surveying equipment consists of a surveying instrument and a tripod. The tripod provides stable support for the surveying instrument, making the measurement results more accurate. Since the surveying instrument needs to be adjusted to different heights during measurement to ensure accuracy and adaptability, existing technology uses telescopic tripods to adjust the height of the surveying instrument to adapt to terrain conditions and meet measurement requirements. However, in actual use, because the tripod needs to be stretched and manually locked one by one, the efficiency of setting up the tripod is low when the measurement points need to be changed frequently during construction surveying, which cannot meet the needs of users.

Multiple connecting rods are rotatably connected to the outer wall of the slip ring. Multiple support rods are fixedly connected to the bottom of the tray, and each support rod is rotatably connected to a corresponding connecting rod. A first spring is fixedly connected to the side of the tray adjacent to the slip ring. Multiple limiting grooves are formed on the top of the tray, and wedge-shaped rods are slidably connected inside each of the multiple limiting grooves. The inner wall of the tripod is fixedly connected with a second spring, and the other end of each second spring is fixedly connected to a corresponding wedge rod. A column is rotatably connected to the top of the tray, and a measuring instrument is rotatably connected to the top of the column. A pull rod is fixedly connected to the right side of the column. Multiple connecting strips are rotatably connected to the outer wall of the column, and one end of each connecting strip is rotatably connected to a corresponding wedge rod. Multiple fixing grooves are opened on the outer wall of the slip ring, and one end of each wedge rod engages with a corresponding fixing groove. An adjustment mechanism is provided at the bottom of the tray for adjusting the tilt angle of the tripod.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes multiple housings, which are fixedly connected to the lower part of one side of a corresponding support rod. A transmission rod is rotatably connected to the top of each housing. The bottom end of each transmission rod passes through the corresponding housing and is fixedly connected to a gear. A sliding groove is formed on the upper part of one side of each housing. A pulling member is slidably connected inside each sliding groove. An internal gear ring is fixedly connected to one end of each pulling member, and the internal gear rings mesh with corresponding gears. A third spring is fixedly connected to the upper part of the inner side of each housing. One end of each third spring is fixedly connected to a corresponding pulling member. A lead screw is fixedly connected to the bottom of each gear. A slider is threadedly connected to the upper part of the outer wall of each lead screw. A supporting hollow rod is fixedly connected to the outer wall of each slider.

[0009] As a further description of the above technical solution:

[0010] The bottom of the measuring instrument is fixedly connected to a turntable, and the outer wall of the pull rod is rounded.

[0011] As a further description of the above technical solution:

[0012] A level is fixedly connected to the top front side of the turntable, and a centering light source is provided at the bottom of the guide rod.

[0013] As a further description of the above technical solution:

[0014] An auxiliary ball is fixedly connected to the right end of the pull rod, and a handle is fixedly connected to the top of the measuring instrument.

[0015] As a further description of the above technical solution:

[0016] Each of the hollow support rods has a triangular cone fixedly connected to its bottom, and a protective sleeve is slidably connected to the bottom of the outer wall of each of the hollow support rods.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when a tripod needs to be quickly set up for measurement using a measuring instrument, the column is rotated by pulling the pull rod. The column then pulls the top of the wedge rod through the connecting strip. The top of the wedge rod is subjected to leverage force, which causes the other end of the wedge rod to lift up, thereby disengaging from the fixing groove and causing the slip ring to lose its fixation. Subsequently, the compression force on the first spring is released, pushing the slip ring downward. The movement of the slip ring opens the support rod, thereby completing the rapid setup of the tripod, improving the tripod setup efficiency, and meeting the needs of users.

[0023] 2. In this utility model, when the horizontal angle of the device needs to be precisely adjusted, the internal gear ring is disengaged from the gear by sliding the pulling member, so that the gear can rotate. Then, the transmission rod is rotated to drive the gear to rotate, which in turn drives the lead screw to rotate. This allows the slider to drive the supporting hollow rod to move downward to adjust the height, so that the device can maintain a horizontal state and ensure the accuracy of the measurement.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a design and measurement device for highway construction, comprising a tray 1 and a measuring instrument 17. A guide rod 3 is fixedly connected to the bottom of the tray 1. A slip ring 4 is slidably connected to the middle of the outer wall of the guide rod 3, allowing the slip ring 4 to slide up and down the outer wall of the guide rod 3. Multiple connecting rods 6 are rotatably connected to the outer wall of the slip ring 4. Multiple support rods 5 are fixedly connected to the bottom of the tray 1, supporting the stability of the tray 1. Each support rod 5 is rotatably connected to a corresponding connecting rod 6. A first spring 7 is fixedly connected to the side of the tray 1 adjacent to the slip ring 4. The first spring 7 is in a retracted state when the device is in the retracted state. Multiple limiting grooves 8 are provided on the top of the tray 1. Wedge-shaped rods 9 are slidably connected inside each of the multiple limiting grooves 8. Second springs 12 are fixedly connected to the inner walls of each of the multiple limiting grooves 8. The other ends of the multiple second springs 12 are respectively connected to the corresponding connecting rods 6. The wedge rod 9 is fixedly connected, the top of the tray 1 is rotatably connected to the column 10, and the top of the column 10 is rotatably connected to the measuring instrument 17. The measuring instrument 17 completes the measurement work and can rotate to measure multiple points. The right side of the column 10 is fixedly connected to the pull rod 14. Pulling the pull rod 14 can drive the column 10 to rotate. The outer wall of the column 10 is rotatably connected to multiple connecting strips 11. One end of the multiple connecting strips 11 is rotatably connected to the corresponding wedge rod 9. When the column 10 rotates, the wedge rod 9 moves inside the limiting groove 8 through the connecting strips 11. The outer wall of the slip ring 4 is provided with multiple fixing grooves 13. One end of the wedge rod 9 is engaged with the corresponding fixing groove 13. The wedge rod 9 plays a fixing role for the slip ring 4. The bottom end of the measuring instrument 17 is fixedly connected to the turntable 16. The outer wall of the pull rod 14 is rounded.

[0034] Specifically, by pulling the lever 14, the column 10 can be driven to rotate at a certain angle. The column 10 pulls the wedge rod 9 through the connecting bar 11, causing the top of the wedge rod 9 to move towards the center. At the same time, the second spring 12 is compressed, and the bottom end of the wedge rod 9, which is subjected to leverage force, lifts up and disengages from the fixing groove 13, causing the slip ring 4 to lose its fixed state. Subsequently, the compressed first spring 7 releases its squeezing force, pushing the slip ring 4 to move downward. The slip ring 4 drives the connecting rod 6 to move. Since one end of the support rod 5 is connected to the tray 1, the action of the connecting rod 6 causes the bottom of the support rod 5 to unfold outward, thereby realizing the rapid unfolding and erection of the device. The turntable 16 can easily rotate the measuring instrument 17 to realize the measurement of multiple points. The outer wall of the lever 14 is smooth after being rounded, so that the operator's hands will not be scratched by burrs during operation.

[0035] Reference Figure 1 , Figure 5 and Figure 6The adjusting mechanism 2 includes multiple housings 201, which are fixedly connected to the lower middle part of one side of the corresponding support rod 5. A transmission rod 202 is rotatably connected to the top of each housing 201. The bottom end of each transmission rod 202 passes through the corresponding housing 201 and is fixedly connected to a gear 203. The transmission rod 202 can drive the gear 203 to rotate. A sliding groove 204 is provided on the upper middle part of one side of each housing 201. A pulling member 205 is slidably connected inside each sliding groove 204. The pulling member 205 can move inside the sliding groove 204. An internal gear ring 206 is fixedly connected to one end of each pulling member 205. The internal gear ring 206 meshes with the corresponding gear 203, and the internal gear ring 206 can... Gear 203 serves as a limit switch to prevent gear 203 from rotating. A third spring 207 is fixedly connected to the upper inner part of multiple housings 201. One end of each third spring 207 is fixedly connected to a corresponding pull member 205, which can reset the pull member 205. A lead screw 208 is fixedly connected to the bottom of each gear 203. A slider 209 is threadedly connected to the upper outer wall of each lead screw 208. When the lead screw 208 rotates, the slider 209 can move up and down. A supporting hollow rod 210 is fixedly connected to the outer wall of each slider 209. The outer wall size of each supporting hollow rod 210 matches the inner wall size of the corresponding housing 201. A knob 24 is fixedly connected to the top of the transmission rod 202.

[0036] Specifically, when the device needs to be adjusted to a horizontal position, the pull member 205 is operated to move it and cause the internal gear ring 206 to disengage from the gear 203. The gear 203 will then lose its limit. Subsequently, the knob 24 is turned to rotate the transmission rod 202. The transmission rod 202 then drives the gear 203 and the lead screw 208 to rotate. The slider 209 then moves up and down, and at the same time, the slider 209 drives the supporting hollow rod 210 to slide up and down inside the housing 201, thereby adjusting the height of the support rod 5 to ensure that the device is horizontal. Then, by releasing the pull member 205, the internal gear ring 206 will re-engage with the gear 203, and the gear 203 and the lead screw 208 will be limited and stop rotating, thus ensuring that the height of the device remains unchanged.

[0037] Reference Figure 1 , Figure 3 and Figure 4 A level 23 is fixedly connected to the top front side of the turntable 16 for observing the horizontal state of the device. A handle 25 is fixedly connected to the top of the measuring instrument 17. An auxiliary ball 15 is fixedly connected to the right end of the pull rod 14. A centering light source 22 is provided at the bottom of the guide rod 3.

[0038] Specifically, the level 23 allows for a more intuitive observation of the device's horizontal state, the handle 25 facilitates lifting and carrying the measuring instrument 17, the auxiliary ball 15 facilitates hand grip when pulling the lever 14, and the centering light source 22 facilitates the precise alignment of the measuring instrument 17.

[0039] Reference Figure 1 and Figure 5 Each of the multiple hollow support rods 210 has a triangular cone 20 fixedly connected to its bottom. Each of the multiple hollow support rods 210 has a protective sleeve 21 slidably connected to its bottom outer wall. The protective sleeve 21 prevents the sharp part of the triangular cone 20 from causing accidental injury. Each of the multiple hollow support rods 210 has an auxiliary foot pedal 18 fixedly connected to one side of its outer wall. Each of the multiple auxiliary foot pedals 18 has an anti-slip groove 19 on its top.

[0040] Specifically, the triangular cone 20 can fix the device on soft soil, the protective cover 21 can cover the triangular cone 20 when it is not in use to prevent accidents, the auxiliary foot pedal 18 can help to step into the ground to fix it, and the anti-slip groove 19 can prevent slipping when stepping on it.

[0041] Working principle: When the device needs to be quickly set up for measurement using measuring instrument 17, pulling the pull rod 14 causes the column 10 to rotate. The column 10 pulls the wedge rods 9 through the connecting strip 11, causing the tops of multiple wedge rods 9 to slide towards the column 10 within their corresponding limiting grooves 8. At the same time, the second spring 12 is compressed, causing the wedge rods 9 to tilt due to the force on their tops, causing their bottoms to tilt outwards and thus disengage from the fixing groove 13. Since the first spring 7 is under compression, after the slip ring 4 loses the tension and fixation of the wedge rods 9, the compressed first spring 7 releases its compressive force, pushing the slip ring 4 downwards along the outer wall of the guide rod 3. Subsequently, the slip ring 4... When the moving link 6 moves, since one end of the support rod 5 is connected to the tray 1, and one end of the link 6 is connected to the support rod 5, the slip ring 4 will expand the bottom of the support rod 5 outward through the link 6 to provide support. This allows the device to be quickly deployed and set up by pulling the pull rod 14. When the device needs to be retracted, pushing the support rod 5 inward will push the slip ring 4 upward through the link 6. At the same time, the slip ring 4 squeezes the first spring 7. When the slip ring 4 moves to a certain position, it will contact the inclined surface of the wedge rod 9, thereby pushing the wedge rod 9 to tilt outward, so that the wedge rod 9 enters the fixing groove 13 to fix the slip ring 4 again, and the device can be retracted from the erected state.

[0042] Furthermore, when it is necessary to adjust the device from an inclined state to a horizontal state, by observing the tilt condition, the corresponding pulling member 205 slides within the slide groove 204. Simultaneously, the pulling member 205 drives the internal gear ring 206 to move together, disengaging from the gear 203. This causes the gear 203 to lose the fixation of the internal gear ring 206 and resume its rotational function. Subsequently, it can rotate via the transmission rod 202, driving the gear 203 and the lead screw 208 to rotate. The rotation of the lead screw 208 allows the slider 209 to move up and down along the lead screw 208. Simultaneously, as the slider 209 moves, it also drives the supporting hollow rod 210 to slide up and down inside the housing 201. By contracting and extending the supporting hollow rod 210 inside the housing 201, the height of one side of the device can be adjusted, so that the device can be precisely adjusted to a horizontal state. Releasing the pulling member 205 will cause the internal gear ring 206 to re-engage with the gear 203, thereby limiting the rotation of the gear 203 and the lead screw 208. The slider 209 and the supporting hollow rod 210 will also be fixed, so that the horizontal state of the device can be kept stable.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
